Copperweld Steel Co. - Specimen Stock Certificate

Inv# SE3308   Specimen Stock
State(s): Pennsylvania

Specimen Stock printed by American Bank Note Company. Copperweld is an American company based in Fayetteville, Tennessee, and maintaining a management office in Brentwood, Tennessee. Its main products are wire and stranded electrical cable made from its Copperweld brand copper-clad steel ("CCS") or copper-clad aluminium ("CCA"). In addition to its American operations, Copperweld maintains a production facility in Telford, England, and a distribution hub in Liège, Belgium.

A group of engineers (S. E. Bramer, Jacob Roth, F. R. S. Kaplan, Simon Loeb and William Smith, Sr.) in the Pittsburgh industrial town of Rankin, Pennsylvania first created a permanent metallurgical bond between copper and steel in 1915. This bond originally was made under a molten weld process. Their product, a CCS wire patented under the brand name Copperweld, was soon adopted as an alternative to solid copper wire in many conductor applications, particularly those where copper would be too ductile or would not offer the breaking strength of steel. The original use, however, was for watch springs: the copper cladding prevented corrosion. The company was founded as the Copper-Clad Steel Company, but in 1924, changed its name to the Copperweld Steel Company. Read more at
